TSM600-400F-2

Ptc Resettable Fuses Overview

The Littelfuse TSM600-400F-2 is a PolySwitch resettable PPTC device designed for surface-mount PCB applications. It features a hold current of 400 mA and a trip current of 800 mA, with a maximum voltage rating of 60 VDC. The component has a maximum resistance of 18 ohms and supports a maximum fault current of 3 A. It operates within a temperature range of -40°C to +85°C and is available in cut tape or reel packaging formats.

Ptc Resettable Fuses Feature Summary

Provides reliable overcurrent protection by raising resistance as it heats to limit current flow during fault conditions.
Designed for surface-mount installation directly onto printed circuit boards to protect components and ICs.
Offers automatic reset functionality after the fault condition is removed and the device cools down.

Ptc Resettable Fuses Applications

Protection of circuits in battery-powered devices
Overcurrent safeguarding for telecommunications equipment
Circuit protection in power supply applications

Ptc Resettable Fuses Procurement Notes

Verify the specific ordering suffix matches the required package type (cut tape vs. reel) and ensure the voltage and current ratings align with the target circuit design. Confirm RoHS compliance status through official Littelfuse documentation before finalizing procurement specifications.

Ptc Resettable Fuses Selection Notes

Select this component based on the required hold current of 400 mA and the 60 VDC system voltage. Ensure the application environment stays within the specified -40°C to +85°C operating range and that the expected fault currents do not exceed the 3 A maximum rating.

Ptc Resettable Fuses Part Context

This part belongs to the TS series of PolySwitch resettable fuses from Littelfuse. These devices are solid-state PPTC fuses intended for automotive, telecom, and general power supply applications, providing a reusable alternative to traditional one-time fuses.
